Thanks for playing. Not sure which version you downloaded, I put up a patch recently which should have removed the crash people kept having.
I appreciate the feedback on which parts of the (temporary) UI are confusing. The number boxes just display the party member's target, which can be changed by clicking on them then hitting NumPad 1-4. Abilities are just activated when in color and will be used on that party member's turn. As far as battle speed, right now it only comes with 2 options. Painfully slow, and way too fast. I'll probably just make it a slider in the next version. It can be changed in the Options menu (ESC).
Party members can be given commands, but it costs Value to do so, so it's not something to do every time. That said, I keep encountering bugs where it doesn't cost value in certain situations.
Art coming as soon as I can scrape together enough to commission an artist or learn2draw.
